Abstract
A overview on application of CO2 in the ironmaking and steelmaking process is presented. Study on resource utilization of CO2 is significant for the reduction of CO2 emissions and the coping with global warming. The paper introduces the research progress of CO2 utilization in the sintering, Blast Furnace, Converter, secondary refining, Continuous Casting and smelting process of stainless steel in recent years in China. According to the foreign and domestic research and application status, the paper analyzes the feasibility and metallurgical effects of the CO2 utilization in the ferrous metallurgy process. The paper mainly introduces such new techniques as 1) flue gas circulating sintering, 2) blowing CO2 through Blast Furnace tuyere and CO2 as a pulverized coal carrier gas, 3) top and bottom blowing CO2 in the converter, 4) Ladle Furnace and Electric Arc Furnace bottom blowing CO2, 5) CO2 as Continuous Casting shielding gas, 6) CO2 for stainless steel smelting, and 7) CO2 circulation combustion. CO2 has a very wide application prospect in ferrous metallurgy process and the quantity of CO2 utilization is expected to be 100kg per ton of steel. It will effectively facilitate the progress of metallurgical technology and strongly promote the energy conservation of metallurgical industry.

The CO2 Utilization is a new subject for ironmaking and steelmaking, which has begun to be studied in the past ten years. The new technological advancements are summarized in this review article, which are not well known. For related field researchers in metallurgical factories and institutions, this article contains many publishable contents, which can not be readed in textbooks. The reference ID [37] is a residual mistake in modify process, and will be corrected soon.

It's really important to put original data and contribution in articles which in your case for example could be: what is your novel plan to make CO2 utilization and green Iron making and Steel making procedures more economically efficient? It's not acceptable to assemble existing literature from internet or existing article in a poor way and make it online even as a preprint. I see in your article you didn't give any original data that is obtained by authors. If your intention is to write a review paper, that's an another story and it's not a correct way to do that.
